Apple Inc.’s iPhone sales in China declined by 24% over the first six weeks of this year, pushing it to fourth among smartphone vendors in the country, according to Counterpoint Research data.

The Cupertino, California company lost the title of China’s best-selling smartphone maker to Vivo, a Dongguan-based manufacturer that did a better job of targeting the budget segment of the market, according to Counterpoint. Both companies registered declines in sales, however, as the overall market in the country was down 7%, casting doubt over hopes for an imminent rebound.
